Dolphin 3.0 has random game-breaking and crashing bugs that are fixed in Dolphin 4.0 and above.
Mac drivers are terrible because they design them themselves instead of using them from Nvidia. So lower the IR and AA/AF to see if you get the same performance as Dolphin 3, and then bring them back up until you hit the slowdowns.
